JOE SCHABHUETTL, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF T0 FELIX SCHABHUE'ITL, OF CHICAGO, ILLINOIS.

VTINDOY V SCAFFOLD.

Application filed May 29,

To all whom it may concern:

Be it known that 1, Jon SCHABHUETTL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Window scaffolds, of which the following is a full, clear, concise,'and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to window scaffolds and the like.

More particularly my invention relates to such supporting devices as are adapted to be detachably mounted in a window casing for supporting or providing a suitable seat for a person wherefrom convenient access to the outer surface of the window may be had for washing the same.

I am aware that supporting devices or window seats of this general description have been provided heretofore in the art. i have observed that such devices have been generally of an expensive and complex construction, many of them being adapted for use in connection with only certain types of window casings, others involving permanent brackets or fixtures mounted in or adjacent the window casing.

My invention aims to provide a supporting device of simple, durable and economical construction, one which may be readily,conveniently and positively secured in almost any size or type of window casing when access to the outer surface of the window is desired for washing the same, painting, glazin or the like.

' i y invention aims further to provide a device or this character which upon being adjusted to a particular window casing is adapted to be removed and arranged in another window casing of the same depth without further adjustment. Thus, for ex ample, in an apartment building or private residence where the depth of the various window casings or frames is substantially the same, my improved supporting device is adapted, upon being adjusted to anyone of the frames to be used throughout the building without further adjustment.

A still further aim of my invention is the provision of 'a supporting "device which although primarily adapted for use as a window seat is of such construction as to which form a part of the present specification, and wherein:

Figure 1 is an outside elevational view of a window showing the window seat of my invention arranged therein;

Figure 2 is an enlarged transverse seci tional view taken on the line 2-2 of Fig ure 1;

Figure 3 is a bottom plan view of the window seat of my invention;

Figure dis a fragmentary sectional view 1 taken on the line l-4L of Figure 3;

Figure 5 is a fragmentary sectional view taken on the line 55 of Figure 3; and

Figure 6 is a fragmentary sectional view taken on the line 6-6 of Figure 2.

Referring first to Figure l of the drawings, the wall 1, shown from the outside, is provided with a sill 2 and a window casing 3 having the usual windows 4 mounted therein.

The supporting device of my invention is adapted to be secured in the window casing 3 when the window a is in the open position to provide a suitable seat wherefrom convenient access to the outer surface of the window may be had for washing the same or performing such other work as painting, glazing or the like. i

The supporting device or window seat comprises a supporting member or seat portion proper 5, shown of fiat r ctangular formation provided with a covering 21, although this is immaterial as the seat may he of any desired shape or form and need not be covered if a covering is not desirable.

A pair of upright supporting pieces 6 and '7 are secured to the under surface of the supporting member or seat portion proper 5, adjacent the opposite ends thereof. Upon arranging the device in a window the sup porting pieces 6 and 7 are adapted to rigidly support the same by the cooperation of the bottom edges with the window casing 8 and the sill 2. The lower outer edges of the supporting pieces 6 and? are securely braced particularly against spreadingby means of a metallic bracing strip 8 secured at its opposite ends to the bracing pieces 6 and 7 respectively and intermediate its ends to the under surface of the supporting member or seat portion proper 5.

A clamping bar '9 is slidably mounted adjacent the inner face of each of the supporting pieces 6 and 7 in suitable channelled brackets 10 and 11. These channelled brackets 10 and 11 which embrace the clamping bars 9 are secured to the under surface of the seat 5 as by means of suitable bolts 12, or in any other desired manner.

. The inner free ends of the clamping bars 9 are hook shaped (Figure 2) for co-operation with the usual horizontal ledge 13 pro vided along the inner edge of the casing 3. The hook shaped portions of the clamping bars-1O and 11 are covered preferably with rubber or some such similar material 14 so as not to mar the window ledge 13 upon clamping the supporting device thereto. Buffers 15, preferably of rubber or some such similar material, are secured to the bottom faces of the clamping bars 9 adjacent the hook shaped portions thereof. The buffers 15 co-operate with the upper surface of the ledge 13, as shown in Figure 2. The hook shaped portions of the clamping bars 9 co-operate with the inner edge and the bottom face of the ledge 18, while the supporting pieces 6 and 7 co-operate with the outer edge of the ledge 13 as shown at 16, with the outer edge of the casing 3 as shown at 17 and with the upper surfaces of the easing 3 and sill 2 as shown at 18 and 19 respectively. It will now be apparent that in a window wherein the depth'of the casing is greater than that shown, the points of co-operation 17, 18 and 19, or even the points 17 and 18, will be suflicient to support the seat 5. Should the depth of the casing 3 be less than that shown the points of co-operation 16, 18 and 19 will securely support the seat.

The clamping bars 9 are slidably adjustable in the channelled brackets 10 and 11 in order that they may readily co-operate with casings of various depths. The channelled brackets 11, one of which is provided in connection with each of the clamping bars 9 are provided with threaded stems 20. the outer ends of which stems are bent so as to be readily grasped to facilitate threading the stems into engagement with the clamping bars are adapted to be moved to any desired position, as shown in dotted lines in Figure 2 to accommodate Window ledges or casings of various depths.

Upon adjusting the clamping bars 9 to a particular window casing such as shown in FigureQ the entire supporting device is adapted to be swung about the hook shaped portions of the clamping bars, removed from the casing and arranged in a similar casing without further adjustment. Thus for example, in an apartment building or private residence where the depth of the various frames or casings is substantially the same, upon adjusting the device to any one of the window casings the same may be used throughout the building without further adjustment.

The supporting device of my invention is of such construction that when not in use as a window seat it is adapted for use in various other capacity. F or example, the seat 5 resting upon the bottom edges 19 of the supporting pieces 6 and 7 and the lower ends of the hook shaped portions of the clamping bars 9 provides either a suitable foot stool or a suitable support for a person in a kneeling position as when scrubhing a floor or the like.

It will now be apparent that I have provided a window seat of simple, inexpensive and substantial construction and this, together with the readiness with which it is adapted to windows of various depths, are highly important aspects of my invention.

lVhile I have described my invention in connection with the details of a particular embodiment I do not intend thereby to limit the invention to such details, as I am aware and contemplate that modifications and changes may be made without departing from the invention which is set out in the appended claims. I

I claim:

1. A window scaffold adapted for mounting in a window casing having a sill and a sub-sill therealong, said scaffold comprising a seat member adapted to overlie said sill and sub-sill and the stool of the window, upright supporting blocks secured at their upper edges to said seat member in spaced relation, said upright supporting blocks having lower edges with offset portions for support ing engagement with the sill and sub-sill respectively, and stationary inner edges for engagement with a substantially vertical shoulder along the window casing, said blocks adapted to support the seat member with its inner portion in spaced relation above the upper surface of the stool of the window, a pair of slidable bars arranged beneath the seat member, means entirely beneath said seat member for securing said bars to said member and guiding them therebeneath, a hook portion at the inner ends masons? of each of said bars, said hook portions being adapted to be hooked over the stool of the window to hold the inner portion of the seat member from swinging up therefrom, means for clamping said bars in adjusted position, said means providing the sole adustment between said hooked portions and the stationary inner edges of the supporting blocks, the device being adapted to be re moved after securing said adjustment and used with similar windows without releasing or re-adjusting the adjustment between said hooked portions and said stationary inner edges, and means carried by said bars for maintaining the spaced relation between the inner ends of the same and the upper surface of the window stool.

2. A window scaffold adapted for mounting in a window casing having a sill and a sub-sill, said scaffold comprising a seat member means for supporting the outer portion of said seat member in overlying relation with respect to said sill and sub-sill and the inner portion of said seat member in spaced relation above the upper surface of the stool of the window, a slidable bar arranged beneath said seat member, means entirely beneath said seat member for securing said bar thereto, and guiding the same therebeneath, a hook portion at the inner end of said bar, said hook portion being adapted to be hooked over the stool of the window to hold the inner portion of the seat member from swinging up therefrom, means for clamping said bar in adjusted position, the movement of said bar forming the sole adjustability of the device to the window and the hook portion at the inner end thereof permitting swinging of the outer end of the seat about said hook portion to permit removal of the device from the window and installation in similar windows without releasing or readjusting said sole adjustment.

In witness whereof I hereunto subscribe my name this 24th day of May, 1919.
